The activity system we were using was built around a separate table.
Whenever the user posted something, or deleted a post, we would sync
the table. The advantage of this was that we could aggregate activity
of all different types very efficiently.
It turns out that it came with a huge disadvantage: there was no
efficient way to enforce permissions on activity. If a user posted
something in a private tag, everyone could still see it on their
activity feed. My stopgap solution was to only sync activity for posts
that are viewable by guests, but that was way too limited.
It also turns out that aggregating activity of different types is
really not that useful, especially considering most of it is the user
making posts. So I've gotten rid of that whole overly-complicated
system, and just made the user profile display separate lists of posts
and discussions, retrieved from those respective APIs. The discussions
page is an actual discussion list too, which is pretty cool.
It's still technically possible to aggregate different activity types
(basically just aggregate API responses together), but we can do that
later if there's a need for it.
This is probably my favourite commit of the day :)
- Use JSX for templates
- Docblock/comment everything
- Mostly passes ESLint (still some work to do)
- Lots of renaming, refactoring, etc.
CSS hasn't been updated yet.
- Return all discussion post IDs from API requests which add/remove
posts, so the post stream updates appropriately. Related to #146
- Always unload posts that are two pages away, no matter how fast
you’re scrolling
- Retrieve posts from cache instead of reloading them
- Fix various bugs. Maybe #152, needs confirmation
- Use contextual namespaces within Flarum\Core
- Clean up and docblock everything
- Refactor Activity/Notification blueprint stuff
- Refactor Formatter stuff
- Refactor Search stuff
- Upgrade to JSON-API 1.0
- Removed “addedPosts” and “removedPosts” relationships from discussion
API. This was used for adding/removing event posts after renaming a
discussion etc. Instead we should make an additional request to get all
new posts
Todo:
- Fix Extenders and extensions
- Get rid of repository interfaces
- Fix other bugs I’ve inevitably introduced
It works but it’s not the most pretty thing in the world. @franzliedke
Would be great if you could take a look at the whole formatting API and
work your magic on it sometime… my brain is fried!
Originally the user activity feed was implemented using UNIONs. I was
looking at make an API to add activity “sources”, or extra UNION
queries (select from posts, mentions, etc.) but quickly realised that
this is too slow and there’s no way to make it scale.
So I’ve implemented an API which is very similar to how notifications
work (see previous commit). The `activity` table is an aggregation of
stuff that happens, and it’s kept in sync by an ActivitySyncer which is
used whenever a post it created/edited/deleted, a user is
mentioned/unmentioned, etc.
Again, the API is very simple (see Core\Activity\PostedActivity +
Core\Handlers\Events\UserActivitySyncer)
Perhaps also in user activity stream. They are used in the mentions
extension.
In order to generate the excerpt, each formatter can implement a
“strip” method which basically converts block formatting into inline
formatting.
